How can I save movie trailers

iMovie allows a movie, trailer or clip to be attached to an email using Mail, the macOS email program.

When you share a movie, trailer, or clip by email, a notification window will let you know if the file exceeds the recommended maximum size for email attachments of 10MB.

Share by email

  1. Select a film, trailer or clip in the overview.

  2. Click the Share button on the toolbar, then click Email.

  3. In the dialog box that appears, do one of the following:

    • Enter a name for the shared movie: Click the name at the top and enter a new name.

    • Enter description for the shared movie: Click on the "Description" field and enter new text.

    • To use tags for the shared movie: Click on the "Tags" field and add tags, separated by commas.

    • Set the resolution for the split movie: Click the Resolution pop-up menu, then choose an option.

      Note: You can export a 4K clip or movie in its native resolution.

  4. Click on "Share".

    An activity indicator is displayed on the right in the toolbar. Click this activity indicator to view details. As soon as the process is completed, the activity indicator disappears again.

    When the process is complete, the movie will appear with the project name as the subject in a draft email. The message “Export successful” is also displayed.
